Introduce enic module global variable enic_numa_count[] to store the
number of affinity_hints set. If there are more than one enic interfaces,
we do not want them to share same affinity hint cpus. We store the
history of affinity hint assignment of all interfaces in global variable
enic_numa_count. Introduce enic_affinity_hint spinlock to access
enic_numa_count.
